Lipoma is the most common tumor of the human body, but their presences in the oral cavity are very rare. Reported cases of lipoma of tongue in English literature are very few. Here, we report a case of lipoma of tongue in 63-year-old male patient, with its clinical presentation, the histological picture, classification, and brief review of the literature.

Aims: The aim of the study was to assess the awareness of the patients regarding implant-retained prosthesis as an option for tooth replacement and the knowledge about tooth replacement as a whole including source of information and attitude towards it amongst Malaysian population. \Materials and Methods: Information on demographic characteristics, knowledge about implant as an option for missing tooth replacement, source of information and knowledge about other options of tooth replacement were obtained from patients visiting various dental outpatient departments of hospital and private dental clinics using nationwide self-explanatory survey. Results: Amongst the 1013 response retrieved, 27% of respondents felt moderately well informed about the dental implant treatment. Only 9% of the respondents had dental implant treatment before and 17% felt well informed about different alternatives of replacing missing teeth. The dentists were the main source of information regarding dental implant treatment modality followed by friends and electronic media. 55.6% respondents felt implant to be as good as own teeth during function whereas high cost was the major limiting factor for implant treatment. Conclusion: 56% of Malaysian population was aware of dental implant as an alternative for replacing missing teeth. Necessary efforts and measures should be made to raise the awareness of dental implant treatment in the country.

Objective: Foreign bodies can be deposited in the oral cavity either by traumatic or iatrogenic injury. The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies. Materials and Methods: From March 2012 to January 2014, 11,144 panoramic radiographs were taken and retrospectively reviewed. The number, characteristics, location of the foreign bodies, age, and gender of the patients were recorded. Results: Of the 11,144 patients reviewed, 62 of them have a foreign body with a frequency of 0.6%. The patients who had a foreign body were between 14 and 81 years old. Female patients showed more foreign bodies than male patients. Among the 62 patients, 63 filling materials, one stapler, and five shrapnel were detected. Only 8 patients had symptoms associated with foreign bodies and these foreign bodies excised surgically. Conclusion: If possible, these pathologies must be removed at the time of detection to prevent further complications; however, in asymptomatic cases, according to location and the characteristic of the foreign body, they can be kept under observation without performing any operations.

Aims: The aim was to evaluate and compare the antimicrobial efficacy of an oxazolidinone (linezolid [LZ]), lantibiotic (nisin), and calcium hydroxide against Enterococcus faecalis biofilm formed on tooth substrate after 2 and 7 days. Methods: Single rooted human mandibular premolars were decoronated, biomechanically prepared, and vertically sectioned along the midsagittal plane to obtain a standardized tooth substrate. Standardized suspension of E. faecalis and tooth substrate was incubated for 3 weeks to allow growth of biofilm. At the end of 3 weeks, the grouping was done according to the medicament used – Group I - LZ, Group II - nisin, Group III - calcium hydroxide, Group IV - negative treatment. Disk of the medicaments used were prepared and placed upon Petri dishes along with bacterial emulsion on Mueller-Hinton agar. The zones of inhibition were checked after 2 and 7 days. Statistical Analysis Used: The scores were statistically analyzed using Tukey honest significant difference test and one-way analysis of variance. Results: Zone of inhibition obtained with LZ was widest followed by nisin and calcium hydroxide after a period of 2 days (P < 0.001). The size of the zone of inhibition remain unchanged for LZ and nisin group after 7 days (P > 0.001) unlike calcium hydroxide group where the zone decreased (P < 0.001). Conclusion: LZ showed maximum antimicrobial potential against E. faecalis biofilm followed by nisin and calcium hydroxide after 2 and 7 days. The antimicrobial effect of LZ and nisin was not affected with the lapse of time, but that of calcium hydroxide significantly decreased.

Introduction: Noncarious tooth surface loss is a normal physiological process occurring throughout the life, but it can often become a problem affecting function, esthetics or cause pain. Aim: The purpose of this study was to assess the effect of erosive and abrasive challenges on the surface microhardness and surface wear of enamel and three different restorative materials, that is, nanofilled composite, microfilled composite and resin-modified glass ionomer cement (RMGIC) by using Vickers microhardness tester and profilometer respectively. Subjects and Methods: Nanofilled composite (Filtek ™ Z350 × T), microfilled composite (Heliomolar ® ) and RMGIC (Fuji II LC) were used in the study. Results: Nanofilled composite resin has the best resistance to erosion and/or abrasion among all the materials tested, followed by microfilled composite and RMGIC respectively. Conclusion: Toothbrush abrasion has a synergistic effect with erosion on substance loss of human enamel, composites, and RMGIC. The susceptibility to acid and/or toothbrush abrasion of human enamel was higher compared to restorative materials.

Epidermal nevi are hamartomatous lesion and its association with other developmental defects particularly of the central nervous system, eye and skeletal system are well recognized. We report a rare case of inflammatory linear verrucous epidermal nevus syndrome along with regional odontodysplasia; and to the best of our knowledge this is the second case reported in the literature.

Central odontogenic fibroma (COF) is an uncommon tumor that accounts for 0.1% of all odontogenic tumors; it has been defined as a benign neoplasm of the jaw. Clinically, the lesion grows slowly and leads to cortical expansion. Radiologically, the most common finding is multilocular radiolucency. The lesions are associated with the crown of an unerupted molar, premolar, or incisor tooth and in some cases, with root resorption or displacement. Histologically, the lesion is characterized by mature collagen fibers and numerous fibroblasts. COF responds well to surgical enucleation with no tendency for malignancy or recurrence. We report a case of a 15-year-old female patient presented with painless swelling of the left side of the maxilla since her childhood. Radiographs revealed an expanding ill-defined radiolucency with a displacement of the adjacent tooth. The impacted tooth was pushed posteriorly. The lesion was removed surgically. There were no postoperative complications.

Aim of the Study: The purpose was to assess orthodontic treatment need in a subpopulation as assessed by the orthodontists. Materials and Methods: The study was conducted on a sample population of 753 patients aged 20–25 years to assess the need for orthodontic treatment using the esthetic component (AC) of the index of orthodontic treatment need (IOTN). Results: The AC revealed that 78.1% of the sample exhibited no or slight need for treatment, 13.2% demonstrated moderate to borderline need, and 8.7% proved to have a definite need for orthodontic treatment. Conclusions: The AC-IOTN can definitely be considered to be used as a powerful tool for prioritizing orthodontic triage, patient counseling, and planning desired orthodontic mechanotherapy.

Ameloblastoma is an epithelial odontogenic tumor exhibiting diverse microscopic pattern that occurs singly or in combination with other patterns. This article describes a case of granular cell ameloblastoma (GCA) involving mandible in a 55-year-old male. The possibility of granular component is there in other odontogenic and nonodontogenic lesions. Sometimes dilemma exists in the diagnosis of such lesions. The purpose of this article is to unveil the hidden characteristics in GCA, which might help in differential diagnosis of GCA.

Minor salivary glands have an important role in the physiology and pathology of the oral cavity though they have been neglected at times. Smoking has a direct effect on the palatal minor salivary glands, and their most common presentation is stomatitis nicotina. We report a case of ulceration in the palatal salivary gland presented with intermittent heavy bleeding from the lesion.

Introduction: Obtaining a correct working length is critical to the success of endodontic therapy. The aim of this clinical study was to compare the effect of working length determination using radiovisiography (RVG) and two-dimensional (2D) and three-dimensional (3D) measurements using cone-beam computed tomography (CBCT). Materials and Methods: Thirty mandibular teeth were taken and three groups of 10 each were made. Teeth with previous endodontic treatments, metal restorations, resorptions, incomplete apex formations, and multiple visible foramina were excluded. The root canal length was determined using RVG, CBCT measurement method 2D, and CBCT measurement method 3D. The difference between CBCT measurements, RVG, and the actual canal length were compared to evaluate the accuracy of each method. Results: No significant statistically difference was seen with 3D measurements and actual measurements. Measurements with RVG were better than CBCT 2D. Conclusion: Under experimental conditions, CBCT 3D measurements are accurate than RVG and CBCT 2D in the determination of root canal length.

The presence of a curve of Spee (COS) of variable depth is common finding in the occlusal arrangement and is sixth key of occlusion The understanding of COS in the field of orthodontics is very important as orthodontists deal with it in virtually every patient they treat. An excessive COS is a common form of malocclusion that may be addressed in many ways, including posterior extrusion, anterior intrusion, and incisor proclination. The specific approach to leveling of COS should be selected based on each patient's needs. Soft tissue, crown–gingival relations, occlusal plane, and skeletofacial concerns are among the special considerations for treatment planning for leveling of COS.
